Android :: Writing Files To SD Card Failing?
Feb 7, 2009
I'm writing an podcast playing application. The application has pre- defined feeds but I want to cache the image of the feed for 30 days. However, on the initial creation of the podcast I am downloading the image, and trying to save it to the SD card using the code below:
CODE:............................
However, it keeps failing on the line k.createNewFile(); with the error: WARN/System.err(10727): java.io.IOException: Parent of file is not a directory: /sdcard/twitcast/1.jpg
I've checked and I have write permission and the SD card is mounted, and I have android.permission.MOUNT_UNMOUNT_FILESYSTEMS included in my manifest. why this keeps failing?

I wrote an app that downloads web sites and all their assets (images/stylesheets) to "disk" and therefore stores lots of small files on the SD card.
Sometimes it fails to delete large amounts of files and afterward the file system is r/o. To analyze that behavior I tried to do the removal of the files by hand and then go from there. But that already failed.
localhost:~ mkamp$ adb -d shell mount [.. some mounts ..] /dev/block/mmcblk0p1 /sdcard vfat rw,dirsync,nosuid,nodev,noexec,uid=1000,gid=1000,fmask=0711,dmask=0700,codepage=cp437,iocharset=iso8859-1,utf8 0 0 --> R/W
Last login: Wed Mar 18 19:41:49 on ttys005 localhost:~ mkamp$ adb -d shell rm /sdcard/newsrob/a* [.. minutes of silent deletes ..] rm failed for /sdcard/newsrob/a2aade03616c28b30_113.png, Read-only file system localhost:~ mkamp$
localhost:~ mkamp$ adb -d shell mount [.. some mounts ..] /dev/block/mmcblk0p1 /sdcard vfat ro,dirsync,nosuid,nodev,noexec,uid=1000,gid=1000,fmask=0711,dmask=0700,codepage=cp437,iocharset=iso8859-1,utf8 0 0 --> R/O now
The log contained nothing but the usual gc output and random WiFi status changed mumbo jumbo.
Anybody else seeing this behavior?
There were 6.500 files in that directory. Might that be the problem? I don't access the files with queries, I always have the exact name.

When implementing download function it work but during file saving to sdcard i get the following Default buffer size used in BufferedInputStream constructor. It would be better to be explicit if an 8k buffer is required.Also IO Exception occure

I have an app that is working, all is cool. Now, it has textview object, and I would like to save that content to *.txt file, in a "simple" way (not for me obviously). I have a simple button, and by clicking it I would like to save *.txt file to SD card, (root of the card is ok).

My Sandisc 64GB SD card went kaputt last week, it froze at 33GB, luckily the existing files are all ok and I was able to copy all the files onto my PC, however nothing new can be written to it. I've tried formatting with no success. So I copied the files onto the PC and just got a new this time Samsung 64GB micro SD card. Problem I'm having now is that on several attempts it's failed to copy the files back to my SD card (from PC) I've formatted the card in the Note 3..the music files about 4 GB transferred just fine, the problem seems to be with the Pix and Videos. I'm currently trying to copy the DCIM folder back onto the micro sd and it's saying it'll take 6 hours.
I have tried: copying from PC to micro SD in the phone via USB copying from PC to micro SD in SD card adapter plugged directly into PC
copying from PC to micro SD in USB adapter plugged into PC
all results the same

My application needs to do some clean up. I need to list the files such as "ls voice*.amr", and then delete those files. How could I do it in Android?

I think we really need a file manager for the g1 so that we have a single app to access all the file on the internal or sd memory instead of going to each appropriate program for the files wanting access to.Secondly, what are the requirement for files on the sd card? Do they all have to be jumbled together in the root directory or can the be organized into folders and still be found by the programs?

I would like my users to develop their own routines for image manipulation. Lets presume that a third party has written a class which implements one of my interfaces; public abstract class PixelBinaryFilter extends BinaryFilter{protected abstract int generatePixel(int p1, int p2);}

I have an app which stores some files on the SD Card. After several uninstall and install, sometimes, the files just got deleted. Is that normal for android os to do that? What should I do to make sure that those files won't be deleted automatically?

I have a Motorola Droid, it is not rooted and I am currently in a deployed location and have no service/access to any networks. My phone got a little wet, but still works for the most part and I want to factory reset it without losing my apps/music/contacts/pictures etc. Is there a way to move all of this stuff to the SD card using and explorer straight from the phone without using a computer? I am out of options.

I havent been able to find the zip or rar files my phone downloads (or at least I think it has downloaded) through the Browser app.
THe very first time I tried this it worked fine. i downloaded a zip file from filestube and it immediately showed up in the notification bar that it was downloading. When it was done i clicked the notification and i unzipped it with androzip or something like that. Worked like a charm...
But now i have tried many times, and i never get any confirmation that any download has begun in the notification bar or anything. The only thing that leads me to believe that some download is actually taking place is that, for instance, if iam downloading from megaupload, if i click the download button 2x it will take me to window saying that "this i.p address is already downloading a file".
But i cant find any evidence of this on the phone? I have looked through all the folders on the sd card, but no luck.

I'm happy reading and writing to a pre-set file, and could manually populate a listview, but I'm hoping there is an official(or not) filebrowser I missed, or other more elegant solution to present the user with a directory listing, and let them select a file.

I am trying to create a folder and several subdirectory within it on the SD Card... I then want to transfer files that I have stored in /res/raw to that folder... I addition, I want this to only happen once, the first time the program is ever run. I realize that this is ridiculously open-ended, and that I am asking a lot...

I"m always connected by wifi at home and i would like to access my files through wifi. There are a lot of web browser based wifi apps (like Websharing) but I was wondering if there are any drag and drop methods as if I was connected by the USB cable. I want to access the SD card through My Computer and not Firefox.

I have a project written for Android devices. It generates a large number of files, each day. These are all text files and images. The app uses a database to reference these files.
The app is supposed to clear up these files after a little use (perhaps after a few days), but this process may or may not be working. This is not the subject of this question.
Due to a historic accident, the organization of the files are somewhat naive: everything is in the same directory; a .hidden directory which contains a zero byte .nomedia file to prevent the MediaScanner indexing it.
Today, I am seeing an error reported:
CODE:................
Regarding the sdcard, I see it has plenty of storage left, but counting
$ cd /Volumes/NO_NAME/.hidden
$ ls | wc -w
9058
Deleting a number of files seems to have allowed the file creation for today to proceed.
Regrettably, I did not try touching a new file to try and reproduce the error on a commandline; I also deleted several hundred files rather than a handful.
However, my question is: Are there hard limits on filesize or number of files in a directory?
am I even on the right track here?
Nota Bene: The SD card is as-is - i.e. I haven't formatted it, so I would guess it would be a FAT-* format.
The FAT-32 format has hard limits of filesize of 2GB (well above the filesizes I am dealing with) and a limit of number of files in the root directory. I am definitely not writing files in the root directory.

I see how to mount an SD card in the emulator, but I'm not sure how you move files back and forth between the userdata image and the SD card image. Can someone tell me how to do this?

Ok so I wiped and formatted my SD Card to FAT32. I am in the reboot/recovery screen of my android with ClockworkMod and I noticed when I turned on USB Mass Storage, the SD Card is readable but there is nothing on it now. Is there any important files I am going to need to put on the SD Card for my android to function correctly on start up/running? Or will my android automatically put the correct files on the SD Card on boot? Haven't tried booting it .
